Test zone: Press "Now" button to get an operation to be solved. In some cases also you need to select how big (in digits) do you want the numbers. Keyboard zone: To write your answer. Please, give time to each key to send its information to "your answer" window. Press "Enter " when ready or "Cancel" if you make a mistake. Report zone: See here your results. If the "stopwatch" doesn't stop, that's probably because the "now" button has been hit repeatedly, in this case press again "Enter" button.
